Blanks in diagram names lead to missing image of diagram preview

[rnwolf]

No image being rendered for pantuml diagram below. Is it possible to specify the location of the pantuml.jar to use? Alternatively it seems that it might be possible to update the version of
asciidoctor-diagram?
It seems like the current version is name="org.asciidoctor:asciidoctorj-diagram:1.5.0"
And the latest version is 1.5.19.

This does not work:

[plantuml,'This is a header',png]
----
@startgantt
[Task1] lasts 10 days
then [Task2] lasts 4 days
-- Phase Two --
then [Task3] lasts 5 days
then [Task4] lasts 6 days
@endgantt
----

This does work fine:

[plantuml,'Helloworld',png]
----
@startuml
Alice -> Bob: Authentication Request Bob --> Alice: Authentication Response
Alice -> Bob: Another authentication Request Alice <-- Bob: another Response

Thank you for reporting this.

The second parameter is actually the file name and not a header. I found that the current plugin version doesn't handle blanks in file names for previews of images.

The following diagram works for me:

[plantuml,'diagram',png]
----
@startgantt
[Task1] lasts 10 days
then [Task2] lasts 4 days
-- Phase Two --
then [Task3] lasts 5 days
then [Task4] lasts 6 days

Please note that all file names need to be unique within your document so that one diagram doesn't overwrite another.

The plugin include AsciidoctorJ-Diagram 1.5.18, the latest version available of AsciidoctorJ-Diagram. This in turn include the Apache-licensed PlantUML library. To show the version of the bundled PlantUML library, please use:

[plantuml,info,png]
----
@startuml
version

This states 1.2019.06 for the latest (preview) release of the plugin.

I've address this in pre-release 0.30.3. Blanks in diagram's file names now work in the preview.

The new pre-release of the plugin is available from GitHub releases and the IntelliJ AsciiDoc EAP repository.
